A comparison of observed (absolute) survival rates was made for 890 black and 24,372 white female breast cancer cases diagnosed at age 24-84 years from 1976 to 1981 while residents in Upstate New York, using data on passive follow-up as reported to the population-based New York State Cancer Registry. Although survival rates were significantly lower in black vs. white cases at 1 and 3 years after diagnosis for all stages combined, racial differences in survival within each clinical stage were small. Noteworthy were the nearly identical survival rates for blacks and whites diagnosed at stage 1 (local disease). Thus, black-white differences in socioeconomic status, especially when stage at diagnosis is considered. Within clinical stage 3 (metastatic) cases, however, survival tended to be poorer in younger (less than 60 years) black vs. white patients. These data suggest the need for programs aimed at early detection of breast cancer among black women at younger ages.
利用上报给以人群为基础的纽约州癌症登记处的被动随访数据，对1976年至1981年期间居住在纽约州北部、年龄在24至84岁之间的890例黑人女性乳腺癌病例和24372例白人女性乳腺癌病例的观察到的（绝对）生存率进行了比较。尽管所有分期合并后，诊断后1年和3年时黑人病例的生存率显著低于白人病例，但每个临床分期内的生存种族差异较小。值得注意的是，诊断为1期（局部疾病）的黑人和白人的生存率几乎相同。因此，黑人和白人在社会经济地位上存在差异，尤其是在考虑诊断分期时。然而，在临床3期（转移性）病例中，年龄较小（小于60岁）的黑人患者与白人患者相比，生存率往往更低。这些数据表明，需要开展旨在早期发现年轻黑人女性乳腺癌的项目。
